The quillback, also known as the quillback sucker or quillback carpsucker, is a type of freshwater fish of the sucker family widely distributed throughout North America. It is deeper-bodied than most suckers, leading to a fuller-bodied appearance. However, the quillback is not a carp. Quillback are catostomids, and like all catostomids, they do not have barbels around the mouth. The quillback is long-lived, with age up to 30 years found in Florida, and lifespans of 44 - 52 years in Canada, Minnesota, Colorado, and Wisconsin.
